The 14-day calorie-controlled diet was created by Dr Herman Tarnower.
Its specific ratios of 43pc protein, 22.5pc fat and 34.5pc carbohydrate saw women consume between 650 and 1000 calories per day. Thanks to promotion in Vogue it became one of the best-selling diet books of the 1970s.
1980s: Slim Fast
